摘要：

Electron-H2 scattering at low energies is treated by an efficient numerical solution of the two-dimensional Schrodinger equation including the nonlocal exchange interaction. Correlation within the scatterer is included but polarization and short-range free-bound correlation are omitted. The elastic differential cross section is well described for scattering angles larger than about 30°-45° and for energies up to at least 5 eV. The scattering function is analyzed in terms of spherical harmonics; the expansion is slowly convergent in the region 0.6-1 Bohr radii, with significant contributions as high as 1=10. The position of the observed broad resonance at about 3 eV is accounted for by the model in terms of the p, wave, but it is inferred that free-bound correlation is necessary to account quantitatively for the width.
